Recurrent superficial sediment failure and deep gravitational deformation in a Pleistocene slope marine succession: the Poseidonia Slide (Salerno Bay, Tyrrhenian Sea)

Presented by Ms. Francesca BUDILLON on 23 Sep 2013 from 17:15 to 19:15
Type: Poster presentation
Session: Poster session


A large number of exposed scars, originated by multievent sediment failures, have been identified on the southern flank of a deep submarine valley in Salerno Bay (Southern Tyrrhenian Sea), between depths of 300 m and 700 m. A 200 km2 complex slide lies across a 17 km-long SW-NE trending anticline, which is exposed 40 m above the seafloor of the continental slope and folds a Pleistocene marine successions. The exposed anticline, as well as others which are more subdued, have been formed by gravity-driven deformation of a deep and unconsolidated slope succession. The deep deformation seems to be coeval with recent stages of regional tectonic activity, given that a regional unconformity related to MIS 6 lowstand seals both the deep slide features and the fault planes. A combined dataset of 2D high resolution seismics, swath-bathymetric digital elevation model of the seafloor and a gravity core was used to establish a possible relation between recurrent sediment failures at the seabed and the stack of positive reliefs in the compressional toe region of the buried slide system and to learn more on the timing of the deformation phases.
